Problems solved by technology

The disadvantages of these two applications are that the dyeing method is dyeing, the dyeing process wastes a lot of dyestuff, the dyeing process is long, the temperature control requirements are high, the process is complicated, and a large amount of water is needed after dyeing. The dyeing effect of the same dye on different fibers is quite different after rinsing.

Embodiment 1

[0057] Cotton loose fibers are arranged to form a cotton fiber web with a thickness of 5mm. The cotton fiber web is transported to the physical pretreatment area by guide rollers, and the cotton fiber web is subjected to ozone treatment. The ozone treatment device adopts a corona device, and the transfer device can use a conveyor belt. The speed is 5 m / min, the working height between the corona treatment device and the cotton fiber web is 5 mm, and the concentration of ozone is 20 mg / L. After the ozone treatment, the cotton fiber web is guided by a guide roller and immersed in 15g / L cationic modifier FK-316, 8g / L fatty alcohol polyoxyethylene ether (JFC), and modified fatty alcohol polyoxyethylene ether can also be used. 0.1% γ-glycidoxypropyltrimethoxysilane, 0.1% ammonium persulfate solution treatment pool, the bath ratio is 1:20, the temperature of the chemical pretreatment solution is 90°C, and then the soaked cotton fiber The web is guided to the roller through the guide ...

Abstract

The invention relates to a pigment dyeing method for loose cotton fiber, in particular to a pigment dyeing method for subsequently performing physical and chemical pretreatment on the loose cotton fiber, and belongs to the field of textile printing and dyeing and processing. The loose cotton fiber needs to be subjected to the physical and chemical pretreatment; the physical treatment can improve the surface area and the chemical activity of the cotton fiber; and in the chemical treatment process, a direct bonding mode of a pigment and the cotton fiber in the conventional process is changed, the cotton fiber and the pigment are connected at two ends of gamma-epoxypropoxy propyltrimethoxysilicane through chemical condensation reaction, so that the mode of interfacial bonding is increased, the bonding force of the interface is improved, the single bonding mode of the pigment and the cotton fiber in the conventional process is changed and the color fastness is improved.

Description

technical field [0001] The invention relates to a cotton loose fiber paint dyeing method, which belongs to the field of textile printing and dyeing processing. technical background [0002] Dyeing and finishing endow textiles with different color styles, and the development of textile dyeing and finishing technology makes dyeing not only include dye dyeing but also paint dyeing. The traditional dyeing process requires more than 100 tons of water to dye one ton of fabric, and the discharge of wastewater after dyeing is large and the pollution is serious. Pigment dyeing has the advantages of small water consumption, short process and low cost. At present, it is widely used in textile printing and dyeing industry. my country's paint dyeing began in the 1980s. After decades of development, paint dyeing has received more and more attention. However, the proportion of paint dyeing in the dyeing and finishing industry is relatively low compared with western developed countries. ...
